Specification of Letters Patent.

Patented May 28, 1907.

Application filed April 9, 1906- Serial No. 810,750.

To a, whom it 7%001/ concern:

Be it known that I, BENJAMIN MOINNERNEY, of Omaha, Douglas county,Nebraska, have invented a new and useful Improvement in Means of Controlfor an Electrically-Actuated Body, of which the following is aspecification.

My invention relates to a means of control for an electrically moved caror body.

The object of my invention is to provide a means whereby an operator candirect the movement of an electrically actuated body from the body orfrom any suitable place. For further object that said operator canregulate and vary the speed of the said. actuated body. And for furtherobject to direct the movement of the said body and simplifying the meanswhen so moved for automatically stopping at any one of any number ofstations. And for further object of so directin the movement of anelectrically actuatec body and reducing the speed and automaticallystopping at selected stations after said speed is reduced. And forfurther object of providing a means for directing a movement of saidelectrically operated body away from such selected station where saidbody may have been automatically stopped and at a reduced rate of speed.And for the further object to provide in connection with such dlrectlon,control and automatlc stoppage, means to insure safety and positiveelectrical action.

Other detailed objects of my invention,

will appear more fully in the description of the same.

My invention consists of a combination and arrangement of switches,circuits and devices which are hereinafter more fully described in thisspecification and the diagrams and drawings.

Figure 1. is a side elevation of gearing intermediate between the powerapplied and the moving body with switches, diagram of circuits andresistances. Fig. 2 is a side elevation of said electrically actuatedbody and a diagram of mechanically operated switch and circuits. Fig. 3is a diagram showing a lneciiai'iicaiiy' operated switch and Fig. 4 is adiagram showing operating switch in Fig. .1 in plurality andinterference switches.

In the drawings and the diagrams my invention is represented as appliedto an elevator car, with the customary intermediate applied to, landingsor stations with diagram of nonworm and gearing in the casing E, andactuated by a motor whose armature is represented in the diagram at y.My invention however is not confined to the control of elevatormachinery, but may apply to any car or body driven by electrical powerand my invention is here shown applied to elevator machinery forconvenience of illustration and not for limitation.

Similar letters and figures indicate like parts through the drawings anddiagrams.

D represents the bar of an operating switch arranged to be moved at thewill of an opera tor, either upon the car as illustrated in Fig.

1, or by any suitable means at a distance from the actuated body asshown in Fig. 2, or

upon landings, or at stations remote from the car as shown in Fig. 4; kand g are the respective line wires furnishing current for the operationof the machine. The lever D is connected to the line 76 by the line k0with (Fig. 1) or makes with the contact piece 34 or 32 (Fig. 2) saidcontact pieces 3 L and 32 connecting with the said line 76 through lineis and switch .9. The contact piece 11 is connected to the solenoid 20of a reversing switch a and the contact piece 11 is oonnected with thesolenoid 21 of a reversing switch cl. The contact ieces 13, 13 areconnected through the line gto the contact pieces 9 of a station switchJ and the contact pieces 14 and 14; are connected through the line 'i tothe contact piece 10 of a station switch J and the line 41 connects withthe solenoid 38 of a line switch .9. are connected through the line jwith the solenoid 39 of a field switch F to the line i. The reversingswitches a and d may have the usual mechanical or electrical means ofinterlocking well known to the art, but where a single operating switchis used as in Fig. 1, I consider this unnecessary for reasonshereinafter shown.

To insure safety of operation and to guard against dangerous or falsemovements of the The contact pieces 15 and 15 driven body by reason ofderangement of reversing switches a. and d, the switch bar D may bedivided with one part insulated from at L and cent-act IIO insulatedfrom it is the switch bar d arranged to connect the contact piece 1.)and 18. The contact piece 17 is connected to the contact piece 11 andthe contact piece 18 to the con- 5 tact 1.1. When the contact pieces 12and 12 (Fig. 1) are not used there is no insulation 1.! in the lever Dof the operating switch and said lever D is arranged to be moved, andconnect when in the position 2, the contact piece 11 and 13; when movedto the position -3-to connect the contactpieces 1.], 13 and 1 1; andwhen moved to the position 4 to connect the contact pieces 11 and 15.And likewise when the said lever D without the nsulation 15 L is movedto the position of 2 it connects the contact pieces 11. and 13 and whenmoved to the position 3 connects the contact pieces 11, 13 and 14; andwhen moved to the position 1 said lever connects contact pieces 11 with15. When the contact pieces 12 and 12 (Fig. '1) are used and connectedas aforesaid the ortion of the lever D making contact with t e neces 12,13, 1 1, 15 respectively is insulated from that portion of said 5 leverD making contact with the pieces 11 and 11 respectively by theinsulation L. The line switch 8 is placed in the line is and connectedthrough the line 7c with the reversing switch it and through the line 7:with the reversing switch (2. 1n the line i to the solenoid 38 of saidline switch 8 is placed a switch 24 attached to the starting switch Ifhereinafter described, which switch 24 has the contact pieces 23 and 22in the same line i. 3 5 The reversing switch it connects with contactpieces 32 and 28 when down and 31 and 27 w en up, and the reversingswitch (Z connects the contact pieces 34 and 30 when down and thecontact pieces 33 and 29 when up. The contact pieces 29 and 30 throughthe line b, are connected with one terminal of the armature desi natedup, and the contact pieces 27 an 28 of the reversing switch it connectsthrough the line a with the terminal designated down of said motor. Thecontact piece 33 connects with the startin resistance r and r throu hthe line 9 an the contact pieces 31 of t e reversing switch it connectsthrough the line 9 to the said starting resistance r, 1", part or all ofwhich may be wound upon the motor field core in the usual manner and thesaid resistance r is connected through the line a to the line g. Thecontact pieces 26 of the reversing switch 5 5 a is connected by saidreversing switch to the contact piece 32 when down and the contact piece25 of the reversing switch at connecting, when said switch is down, withthe contact piece 34. Said contact piece 26 and 25 are connected throughthe line e with the solenoid 6, and said solenoid 6 to the line The linef is connected to the solenoid 5 of the starting switch t and thesolenoid 5 is connected to the line g. In the circuit through .the fielda: and m of said motor and connected by the line 0, is placed the fieldswitch F, having the solenoid 39 and the field resistance Fr, saidsolenoid 39 is in the line Said field resistance F r is short circuitedwhen the field switch is closed and said i'ield resistance Fr is thrownin series with said field and a" when the field switch F is opened. Uponany convenient moving element 01' said mechanism is placed the brakewheel in, upon which the brake applied by spring (1 is arranged to actand which is released by a solenoid 6. The line f through the solenoid 5is short circuited through the line Z and the line m to-the line 9 whenthe contact pieces 7 and 8 are connected by the switch '0. The switch vis arranged to break the contact between the pieces 7 and 8 when thebrake is released. Upon any convenient moving part of the intermediatemechanism or attached to it asz are placed movable adjustable pieces29,10, p, p, said pieces corresponding in number to the stopping placesor stations desired and corresponding to the station M, M, and M for theelectrically actuated body 0. The switch bar 0, of the switch J isarranged to connect the contact pieces 9 and 10 except when byirregularity of 2, which may be accomplished in any suitable manner butpref-- erably by projection, of the pieces 19, p, p, 12 etc., the bar 0of the said station switch J is moved to open the said switch.

When the operating switch D is operated by mechanical means at adistance from the moving body C, or where the mechanically operatedreversing switch is used, the respective terminals 27 and 29 of themotor circuit through the lines (1 and b are arranged to connectrespectively with the contact pieces 31 and 32, and the contact pieces33 and 34. The contact pieces 31 and 33 are connected to the line 9 andthe contact pieces 34 and 32 are'connected with the line is. When thebar D (Fig. 2) is in the position 3 the contact pieces 29 and 34:, 13and 14. are connected, and when the said lever D is in the position 4,the contact pieces 29, 34 and 15 are connected and in a correspondingmanner when the lever D is in the position 2, the contact pieces 27 32and 13 are connected and when said lever D is in position 3 the contactpieces 27, 32, 13 and 14 are connected; and when the lever D is in theposition 4, contact pieces 27 32 and 15 are connected. A mechanicallyoperated switch D, as shown in Fig. 2, may either be placed upon themoving body 0 or at a distance from it with suitable means for operatingit. The electrical switches described herein may be replaced by a mechanical switch as shown in Fig. 3. When such mechanical switch isemployed in place of electrical controlled switches a line is connectswith the field m and as, (Fig. 3).

The field coils :13, ac are connected with the contact pieces 61 and 63of the switch D. The line 7a through the line e may connect 20 of thereversing switch a.

with the solenoid 6 of the brake g and through the line f to thesolenoid 5 of the starting switch t (Fig. 3), which said solenoid 5 isconnected to said contact 61 and 63. The line is is connected throughthe line g" (Fig. 3), through the resistances r and r part or all ofwhich may consist of series field coils, and the line 17, to the contactpieces 34 and 32. The contact pieces 31 and 33 (Fig. 3) is con nectedthrough the line 62 to the contact piece 10 of the station switch J(Fig. 3) which connects the contact pieces 9 and 10, which contact piece9 is connected with the line g (Fig. 3). The contact pieces 15 and 15(Fig. 3) is connected to the line 9.

The operating switch D may be used singly or in plurality as shown inFig. 4 with a switch D placed at each landing or station M, M, etc. Whenthe operating switch D is multiplied the line k0 may be connected to aswitch 57 and an emergency stop button 56 may be supplied upon the carC, which said switch 57 when used is by'the line k0 connected to thelever D of the respective station or landing switches. The line k0 (Fig.4) is divided into as many circuits as there are station switches and toprevent interference for operation of .any switch each branch of theline k0 is connected to a' solenoid on the cores kf, kf, kf, 79, of thenon-interference switches Mf Mf,- M"f, of which there is one of suchnon-interference switches for each switch D besides the car switch D.The divided line ice to each operating switch D for landing or stationis connected to solenoids upon the cores Jcf, 7cf, corresponding to thelanding or station of the operating switch D so connected. The operatingswitches D when used in plurality and at stations have the contactpieces 11 connected to the line 7m, and has inserted in each branchthereof, a solenoid upon the core Mic. The line kit is connected to thecontact piece 17 and may be connected to a solenoid id of the reversingswitch (1 and then connected to the solenoid In a similar manner thecontact pieces 11 of the operatingswitches D, when in plurality arecon-.

nected to the line kp, each branch of which is connected through asolenoid upon the core Mk, the line kp being connected to the contactieces 18 of the reversing switch d. The line p may also connect throughthe solenoid Z11. of the reversing switch at and connect with thesolenoid 2 1 of the reversing switch d.

When the switch 57 is not used and when the operating switch D is usedin plurality, the line 150 may be run from the line 7c about each ofthe'cores k], k f Ycf ,]c f etc., (which said contacts on said switchesare connected respectively) and the operating switch D on the body orcar 0. The contact piece 16 is connected through the line 1m to each ofthe non-interference switches M], M ',l\ ,M f, etc. which said contactson sai switches are connected respectively to the contacts on the lines7m, which lines 7m are connected with the contact pieces 12 of theoperating switches D. The contact piece 19 is connected through the linekp to the contact pieces of each of the non-interference switches M f,Mf, M" Mf, etc., which said contacts are by said switches connected tothe lines lap, which lines 7c are connected to the contact ieces 12, 01the operating switches D. The ine kit is also connecteddirectly with thecontact piece 12 and the line kp' is connected with the contact piece 12of the operating switch D upon the car or body C without passing throughthe contacts on the station switches M f, Mf, etc. The remainingcontacts of the operating switches D, when used in plurality arethe'same as already de scribed, when used singly. When the mechanicalswitch, as shown in Fig. 3 is used in plurality as maybe done or whenswitch 57 is used, the line k0 and its branches about the cores kf, k fetc. is omitted. The solenoids 20 and 21 of the reversing switches atand (1 respectively are connected to the line 9 in which may be placedthe usual slack cable switches 51 and door switches 52, 53, 54, 51, etc.The non-interference switches M f, M j, etc. are arranged so that thecores 7; k f etc. have an energy over the cores Mk by any suitable meanspreferable and lever is shown. In the circuit from the line 'L to thesolenoid .38 may be placed a resistance K to pass a cursirable to have asimple and efficient means of control or direction of movement of thebody or car, suchthat an inexperienced person can control such movementaccurately and without especial skill, by having the sim ple knowledgeof the results-following various positions of an operating lever orhandle. It is found exceedingly beneficial to the ma chinery to be ableto reduce the speed of such car or body in starting and stopping, orapproaching a stopping place. It is also well known to those skilled inthe art that to make exact stops, or to stop exactly at the properposition before a station, req uires great skill and experience inturning off current or applying brakes in the ordinary manner, anddemands skill and experience of the operator in choosing the rightmoment in approaching a station, with facility of action at the rightmoment and all involving an exercise of judgment as to speed and time.To start the car in a chosen direction, and then to be able, betweensuch direction of movement and any after selected. station withinvarying reasonable distances therefrom, to automatically stop at suchselected stations at exactly the right position without skill of theoperator will save wear on machinery and annoyance and delay incident toreversing and extra starts to make proper landing and accomplish highlydesirable and useful results. This combined with ability to reduce speedpreparatory to making such automatic stop and to provide for any numberof stops in I 5 either direction with one station switch is of greatbenefit in simplifying and rendering such mechanism-less liable toderangement. With such ability of control by the operator it isnecessary to be able to move the car at its highest speed in eitherdirection between the limits of travel. By the combination of switches,circuits and mechanical devices herein described, I am by my inventionable to accomplish these novel and desirable ob- 2 jects.

0 ience of illustration, it will require movement of the lever D to theright to move the car or bodyC upward and to the left to move it in theopposite direction. To illustrate the operation of this device, as shownin Fig. 1, if

5 the operator desires to move the car or body toward the station M andM the lever D of the operating switch will be moved to the right. Ascontact is made by said lever with the contact pieces 11 and 12 inposition 1,

4 the reversing switchu is operated and contact between the pieces 32,26 and 28 is broken and made between the contact pieces 31 and 27. Whensaid lever D is moved to the position 2, if the contact piece 12- isused and insulation L divides the lever D, a circuit is formedthroughthc contact pieces 17 and 16 to the contact pieces 13 to the line71, and if the station switch J be closed, connecting the contact pieces9 and 10 the solenoid 38 of the 5 line switch 8, will be energized,closing the said line switch 8 and connecting the contact pieces 37 and36, and circuit will then beestablished from the line is through thereversing switch (1 to the line b and the current will enter thearmature at the terminal up moving the ear or body C in the directiondesignated as up. As the said body C moves upward and approaches thestation or landing M, when the moving member 2, carrying the piece p,travels in proportion to movement of said body or car C until it reachesthe landing M when the piece 1)" will operate the lever o of the stationswitch J and the circuit through the solenoid 38 of the line switch 8will be broken opening the same and the current in the armature 3 willcease and the car or body (3 will be stormed definitely at the stationM. By moving the lever to the position 3 contactis formed between thecontact pieces 12 and the contact piece 14; and a current establishedin. the line i, but not in the line it, the point 7) holding the stationswitch J open. The current in the line i through the solenoid 38 to theline 9 will again close the line switch 8 and the body C will moveupward. As the body 0 moves away from the station M at the proper timeand place in its travel, the station switch J is closed until the body Creaches the station l\ when the station switch J is again opened. Shouldthe operator desire to stop at the station M at a convenient distancetherefrom not necessarily exact he will move the lever D to the position2 and the circuit through the line switch 8 will be broken as heretoforedescribed by the station switch J and the said car or body C will stopat the station M.

In the circuit 0, c of the field coils x, m of the operating motor maybe placed a field switch F and field resistance F7". The said fieldswitch F being operated in convenient manner as by the solenoid 39 inthe circuit through the line y. hen the lever of the operating switch Dis brought to the position 4- or 4 a current will be established in theline j opening the switch F and removing the short circuit of the fieldresistance Fr, thereby decreasing the currcnt in the field coils m and xand increasing the speed of said motor. But when the lever of theoperating switch D is brought to either of the positions 2, 3, 2 or 3operating the line switch 8, the field coils as, :n

will be strengthened by short circuiting the field resistance F1" by theswitch F, red doing the speed of the mot-or. Thus when the lever D isbrought to the position 2 the car will be moved upward at a slow speeduntil stopped by the station switch J as described, and when brought tothe position 3 the car C will move upward at a reduced speed, withoutreference to the station switch J. If after the last operation describedthe lever of the switch D be brought to the position 4 the car or body Cwill be given its highest speed until it reaches the next station orlanding succeeding said operation of said lever D. The changing of speedof said motor whose armature is 7 is not limited to strengthening orweakening the field of said motor by said resistance. Fr but may be doneby any other convenient or well known means as adding circuits to thearmature 1/ and by any suitable switch. 4

For the purposes of safeguari'ling the reversing switches a and (Zagainst failure of operation or mechanical derangement of any kind, theinsulation L may divide the lover of the switch D, and by inserting thecontact ieces 12 and 12 and the contact ieces' P P 16 and 17 and 18and'19 respectively. A

failure to operate either of the said reversin switchesu or d wouldresult in inaction ant failure of current in the line switch 8. Bythrowing into the armature circuit in the line a to g, the contactpieces 27 and 31 of the reversing switch it, and in the line b to g ofsaid armature circuit the contact pieces 29 and 33 of the reversinswitch (1 the said reversing switches u an d are electricallyinterlocked in said armature circuit c b. In this manner any failure ofsaid reversing switches to act or any mechanical derangement thereofwill result in inaction, unless one reversing switch is properlyoperated. In case both reversing switches to andd are thrown up or leftup from any cause, the armature circuit will be broken in one or theother of said reversing switches u and d and there will be inaction. Incase neither of the said reversing switches u and d are raised, thearmature circuit will still be broken and the result will be inaction.And in case said reversing switch (1 and u should be disposed in anopposite position from that intended to follow the operation of theswitch D, still there would be inaction by reason of a failure ofoperating current in the proper direction through the contact pieces 12and 12 to the line 7c. It will be readily seen that the line switch .9may also be similarly interlocked for purpose of safeguard in connectionwith this invention.

In place of the electrical reversing switches u and cl may besubstituted the mechanical reversing switch shown in Fig. 2, having thecontact piece 29 connected to the line a and the contact piece 27 to theline b, and the contact piece 31, 33 to the line 9 and the contactpieces 34 and 32 connected to line K; Either of said switches D may beplaced upon the car or body C or may be operated at a distance from it.And said switches may be placed at some convenient distance and operatedfrom the car or body C by any convenient mechanism as the cables 11, tand the lever H.

In the lines ab from the motor, through the lines g,- g and g andconnected to the line 9 by the line it may be placed the usual startingswitch having the resistance r,'r and operating in any suitablemanner oras shown by the solenoid 5 in the line f to g. In the line e to f mayalso be placed the brake solenoid 6, arranged to release the brake gupon the brake wheel to. The solenoid 6 acting upon the brake g may bearranged to operate the lever v breaking the contact between the points7 and 8 slightly in advance of the release of the brake g and of theaction f h arting switch t. Thus when the line switch 8 is closed and acurrent established through the motor'c'ircuit ab a current isestablished through either of the contact pieces 25 or 26 (Fig. 1) inthe line 6, through the brake solenoi 6 and the line f, and

through the line i and. the switch 1) and the line m to the line g,until by the movement of the brake g the switch 'vis opened, when theshort circuit of the solenoid 5 in the line f is broken, and thestarting switch tis actuated throwing out the resistances r, 1". Thusafter the operation of releasing the brake is accomplished theresistance in the motor 01rcuit is thrown out increasing the speed ofthe motor. In case the mechanical reversing switch is used as shown inFig. 2 in place of the electrical reversing switches at and d, the linesfrom the contact pieces 31 and 33pass directly to the line 9 and theline e may connect to the contact piece 40. When the electricalreversing switches to and d are used by inserting the contact pieces 25and 26 the extra safeguard is iven to the action of the reversingswitches or in case both of said r e versing switches are deranged so asto remain up, the brake will still be applied, and in. case both of saidreversing switches are down and brake releases, armature cannot berotated by the load at a dangerous speed because of the dynamic brakingaction through resistance 58 in the line e.

From this description it will be readily the result whenever the stationswitch J is operated with the operating lever D upon the points 13 and13 or when the lever D is brought to its middle position or upon thecontact pieces 11 and 12, or 11 and 12 only. The same objects may beattained by the use of a mechanical switch and direct current as shownin Fi 3. When the switch D is operated in eit er direction as on to thecontact ieces 63 and 83, or 61 and 31 a current will e establishedthrough the field coils w, as and through contact pieces 10 and 9 of thestation switch J to the line 9. When the switch D is operated it is soarranged as to establish a current from the line is through the line 0,solenoid 6 the line f and solenoid 5 to contact ieces 61 and 63. Alsothrough the line g t e resistance r and r of the starting switch 0 throuh the line it to the contact 34 and 32. Wit the switch D operated toconnect the contacts as 63 and 33 the brake Q will be released, thestartin switch twill cut out the resistance of the coi s r, r and acurrent be established from the contact piece 34 to the contact piece 29and in the line a to the armature y' and to the line 9 as described,moving the armature in the direction indicated as down. While operatinswitch Dis in the position inst described. if the lever of stationswitcliJ be actuated by the piece p, the current between the contactpieces 9 and 10 will be broken, the current through the motor arrestedand the brake g ap lied and the mechanism will stop as hereto oredescribed. By

[6 Bahama" moving the lever D upon the contact piece 15 contact piece 13to the line It will be estab- (l lg. .3) the current Wlll be rcestabhsled and hshed, operating the hue switch s as heretothe motor run withoutreference to the operation of the station switch J. In a similar manner,if the bar of the operating switch 1 be moved to the contact piece 31.and 61. the motor will be started in. the direction indi cated as upuntil stopped by the action of the station switch J as described. Whenthe lever of the operating switch 1 is returned to the position oil fromeither of contact pieces 33 or 32 circuits through the motor will bebroken and the brake (1 applied. It is evi dent that the same means forslowing the speed of the motor (Fig. 3) may be used as with the otherelectrically operated means of control. But where the mechanical switchdescribed in Fig. 3 is used, it will not be generally desirable to varythe speed of the motor.

When it is desired to use a plurality of operating switches D asdescribed as a switch for one or more stations or landings it becomesdesirable to so arrange said operating switches D that operating theoperating switch D upon the car or body C can not be interfered with bythe operation of any of the other switches D upon any of the landings orstations and when one of such stations or landings switches has beenoperated it cannot be interfered with by the operation of any other suchlanding or station switch D. To accomplish this result anon-interference switch M f, f, Mff, etc. is provided for each extraoperating switch D besides the one on the car or body C. In theseswitches Mf, Mf, etc. the cores lcf, 7g" etc. have an energy or leverageover the cores M70, etc. In these switches when the core Mk is energizedand the core kf, lcf, etc. are not energized, the contacts between thelines You and lcp are connected.

From thedescri tion heretofore given it will be seen that wiiere theoperating switch at the station M, having the non-interference switch Mfis o erated and the lever of the operatingswitc D is moved, connectingthe contacts 11 and 12, the current is received through the line k0which branch of the line k0 connects to a solenoid on the cores kf,lcf", kf' but not on the core 7cf and the noninterference switches Mf,Mf, Mf, etc. will all be held open by the solenoid in the line k0 to theoperating switch D of the landing M. The current will pass from the linehe to the contact piece 11 of the operated switch D of thenon-interference switch Mf,

operating the switch Mf connecting the line kc and Ice. The current inthe line You will one-rate reversing switch 1. connecting the contacts16 and 17 in the position and the car 0 to move upward as heretoforedescribed. If said lever of operating switch D at the station M be thenmoved to the contact piece 13, current from the contact piece 12 throughfore described, and resulting in the car moving at reduced speed in thedirection designated as upward, provided the station switch J is closed.By moving the lever 01 the said switch .1.) to the contact piece 14- thecar (.1 will move without reference to the station switch J and at thehighest rate of speed. Similarly if the lever of the operating switch Dbe moved to the contact pieces 11 and 12 a current will be established..in. the lines Icy) about the cores Mlr of" the non-interferel'iceswitches Mf, Mf, Mf, etc. and operating the reversing switch d and thenon-interference switch Mf corresponding to the station M at which thesaid lever of operating switch D so manipulated. The line Icy) will thenbe connected to lay) and the contact piece 12 and if the lever is movedto the contact piece 13, the car C will move in the direction indicatedas down, similarly as described. It will readily be seen that wheneverthe non-interference switcl'i M is operated by the movements of theoperating switch D, for that station by reason of the current throughthe line k0, any operation of the other levers,

at the other landings, will have no effect, by a breaking of thecircuits, between the respective lines Ice, Ice and kp and lap". Toinsure further safety of control and prevent inaction and interferenceor action in the wrong direction, the line he is carried about thesolenoid Zd, which has an ener y over the reversin switch (1 in anysuitab e manner, preferab y as here shown by a lever locking the saidreversing switch d, while the revers ing switch a is operated in asimilar manner. In .the line kp is the solenoid Zu, having a levera'geover the reversing switch a, holding the 'sameclown when the reversingswitch d is operated. As an additional means and for the purpose ofgiving the operator upon the car or body C theright of way over theoperator at any station, the switch 57 may be ar ranged to break thecircuitbetween the line k0 and k0 whenever the lever of the switch Dupon the car C is off from the stopped position. The emergency stopbutton 56 may also attach for emergency stopping or throwing off otheroperators at the landings, without o erating the lever of the switch Don the car To insure further safety and non-interference in the use ofthis system on landings or stations and. by plurality of said switchesD, the line ice from the line it may be carried about the cores kf, hff, lcf etc. of the non-interference switches, to the lever of theoperating switch D on the car C, making any and all other switches outof the operating switch D on the car 0 inoperative when it'is inoperation. This method of noninterference is accomplished in a simplermanner by the use of a speedily energizing force over an inferiorenergizing force instead of a large number ofcontacts. which are foundin practice to in danger e1 deranged, fusing and otherwise interferewith.

What I claim and desire to secure by Letters Patent is: r
